Alkylmercury lyase

In enzymology, an alkylmercury lyase (EC4.99.1.2) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are alkylmercury and H, whereas its two products are alkane and a mercury ion.

This enzyme belongs to the family of lyases, specifically the "catch-all" class of lyases that do not fit into any other sub-class. The systematic name of this enzyme class is alkylmercury mercuric-lyase (alkane-forming). Other names in common use include organomercury lyase, organomercurial lyase, and alkylmercury mercuric-lyase.
